Abstract (en)

[origin: EP3910713A1] Provided are a novel structure and composite suitable for a battery, and a battery containing the structure or composite. The structure includes: an electrode layer; an inorganic solid electrolyte layer; and a fluorine-containing polymer layer between the electrode layer and the inorganic solid electrolyte layer, the fluorine-containing polymer layer containing a composite that contains a fluorine-containing polymer and an alkali metal salt.
